Bombyx Afali, Fiibricius (B. Avell.-in.-c, Fair. Oliv.) Variety. 



Bomhyx paUtdus, I lawoitli. Variety. 



The fore wings when expanded vary from 1 to nearly 1^ inch, and in tlie males are of a pale ashy colour, 

 with a brown fascia before the middle of the wing curved inwards, a second beyond the middle, dentate and 

 black, the space between these fasciai being generally darker, with a black spot ; there is also an indistinct 

 dentate streak running near the margin, and a marginal row of black dots ; the hind wings arc mouse-coloured 

 or brownish. The female has the wings brown, with two or sometimes three nearly obsolete waved whitish 

 streaks beyond the middle. Pale varieties of the female occur with the markings nearly as in the male, which 

 Mr. Haworth regarded as distinct under the name of B. pallidus. The larva is black, with yellow hairs, pale 

 fascial, and an interrupted lateral row of white spots ; each segment is also marked with several red tubercles. 

 It feeds on the whitethorn in iMay, and the moth appears in September. It is a comparatively uncommon 

 species, but occurs in the woods near London, Epping, Bedford, and elsewhere. 



ODONESTIS, Germar. (COSMOTRICHE, Hijbner.) 



This genus is at once distinguished from the preceding groups of this section of the family by the large size 

 of the typical and onlj' species, as well as by the elongated beak-like palpi, the slightly waved outer margin to 

 all the short broad wings, the fore ones being acute at the tips, and the very strongly bipectinated antennse in the 

 males ; the abdomen long and tufted at the tip in the males, but thick and conical in the females. The larva 

 has the back furnished on each side with a tuft of short hairs ; the sides of the body are thickly clothed with 

 decumbent hairs, and a larger one on the back of the second segment behind the head as well as on the penul- 

 timate segment. Tho cocoon is spindle-shaped and compact.

This fine, although common insect, varies from 24 to 3 inches in the expansion of the fore wings, which in 

 the male are of a rich reddish buff clouded with fulvous, with two white dots j^laced one above the other, the 

 upper one being the smaller, in the middle of the wing towards tlie costa ; beyond which runs a straight dark 

 line from tiie middle of the hind margin to the tip of the wing, and is succeeded by a more indistinct dentate 

 line ; the hind wings and body are of the ground-colour of the fore wings. The female is altogether paler, being 

 of a delicate fawn colour, but with similar markings to the male. The colours vary occasionally; being either 

 liglitor or darker in both sexes. 



The caterpillar is dark brown, very much freckled with pale dots, a yellowish line on each side, with white 

 tufts of hair along the sides above the feet. It is very abundant in -June, feeding on grasses, the moth appearing 

 in the following month. It is very abundant throughout the country.
